H. H. Hsue and H. Wu (in FRPS 71(1): 249. 1999) described the petioles as ferruginous pubescent, but the protologue description of this species says "petioli glabri nitiduli," though these "petioli" are described as structures belonging to "pedunculus communis" and may be pedicels rather than petioles.

The possibility cannot be completely excluded based on the information available that this name will be found synonymous with Uncaria gambir.
